September 19, 2021 I traveled with my university friends for three days. We went to China prefecture and stayed at cottage by the sea. In the first day, we went through Aqua Line connecting Kanagawa prefecture and Chiba prefecture and took a rest at Umi-Hotaru which is a park area. Then, we arrived at the cottage and had a BBQ. Finally, we talked a lot until late at night. That was really fun. I’ll talk about day-2 tomorrow.
